Not even close. SS1/White Knight cost 20 Million as it stands. And, while it's a danged good acheivement, it was designed to a flight profile that minimized teh need for any advanced materials or systems. (For example, SS1 isn't very fast - only about Mach 2 or so on the ascent, and a bit less on the descent. That menas that you don't have to worry about aerodynamic heating, or hypersonic stability and control, or any of that other fun stuff. So, you don't need exotic materials, literally millions of hours of Wind Tunnel, Shock Tude and CFD time, The X-Prize was about altitude only - you don't need a lot of speed, just impulse. As you can see, you can do pretty good with a fairly low thrust long-burning motor. The flights themselves aren't alll that long, so you can basically build the cabin as a Bathysphere (Aerosphere?), much like a 1930s high altitude baloon gondola. Orbiting something is an entirely different matter. In that case, it's all about speed. Lots of it. Think 25 times the Speed of Sound. That means huge rocket motors, lots of fuel, a much bigger ship, of course, and much dicier aerosynamics in general. That's only on the way up. A couple of orbits is going to be at least 3 hours. That'll mean a Serious environmental control system. Then there's getting the whole thing back down. You've got to go fram Mach 25/ 100 miles up to sitting still on the ground. There's an awful lot of energy there, and it's going to turn into heat. There's nothing you can do to escape that. That means a space shuttle level Thermal Protection System. (And it will have to be a similar system - the re-entry heating is enough to destroy stuff like Nickel-based metals like Iconel-X, let alone Weak Girly Metals like Steel and Titanium. The only way to keep the structure strong is to keep the heat out. All that exotic stuff adds up, but fast. At a guess, 500 Million isn't enough. (THat's basically the cost of a Luxury Boeing 747, these days. A couple of Billion _might_ work. 5 Billion (U.S. Billion, not the British Billion) probably would work. -- Pete Stickney A strong conviction that something must be done is the parent of many bad measures. -- Daniel Webster |

No, but $10 million doesn't cover the cost of Space Ship One and the White Knight. Yet they flew. It would seem that the prize need not cover the costs in order to produce the desired results. Think on that for a while. Also, it's unclear that the $50E6 prize actually being discussed, requires a fully reusable craft. It is *not* a case of, "Exactly like the X-prize only to orbit"; Bigelow will write his own rules, and they may allow for a spaceplane or capsule atop an expendable booster. -- *John Schilling * "Anything worth doing, * *Member:AIAA,NRA,ACLU,SAS,LP * is worth doing for money" * *Chief Scientist & General Partner * -13th Rule of Acquisition * *White Elephant Research, LLC * "There is no substitute * * for success" * *661-718-0955 or 661-275-6795 * -58th Rule of Acquisition * |

For an X-Prize flight a capsule would most likely be the only way to go. And even that would be quite an achievement. If someone can do that safely and cheaply space is all but won. But I doubt that it will be grabbed anytime soon. I would really like to see Rutan coming up with something similar to the feathering mode for orbital reentry but it seems daunting at this time. If he does you can bet that Boeing/Lockmart will copy it in short order. |

Would $50 million be enough(?)
No. It would require some x number of dollars, 200M, 1B, somewhere around there. A good opportunity to develop private orbital flight was missed when Beale Co went out of business here in Texas. A former banker tried to develop a low-cost booster rocket to compete in the sat launch market. He figured he could sell his boosters for $200M, make a good profit, and beat Boeing and others in price. I seem to recall he was also trying to develop his own engines, which I think was a mistake as the Russians have a comparative advantage in this area. The booster designs at Beale featured wound carbon construction, not unlike a large cardboard shipping tube. I think that his company could have succeeded with 1) a high demand for satellite launches and 2) more capital. The weak market for sat launches is not Beale Co's fault. Then there was the unspoken factor of being the new guy, and since the Pentagon and NASA are used to dealing with the major industrial companies, Beale would have had a hard time getting a foot in the door. The amount of capital that Mr. Beale put in to the company was significant, probably $200 million. |

["Followup-To:" header set to sci.space.policy.]
At a guess, 500 Million isn't enough. (THat's basically the cost of a Luxury Boeing 747, these days. (I was rather taken by the analogy someone used that the total program cost of SS1/WK is on the order of two-thirds the flyaway cost of a single F-16.) A couple of Billion _might_ work. 5 Billion (U.S. Billion, not the British Billion) probably would work. The British billion is also bigger values of 1 to start with ;-) 'Course, there's nothing to say that we won't have multiple people offering multiple related prizes, with varying levels of attatched strings; the back of /The Case For Mars/ had an interesting digression on a prize-based scheme (totalling either $10 or $20 bn) to bootstrap a private Mars capacity on the same scale as the NASA reference mission du jour. Not proposing it, but it's worth looking at for an idea of how to structure these things. -- -Andrew Gray |

Boy, you got enough wrong I am not surprise you used Revision as your name.
"Revision" kentnobettsspam@techispdotcom : Would $50 million be enough(?) No. A flat no? How can you know this? Armadillio's appoach sure does not look like they will need so much. A lot depends on the assumations of what the final craft must be able to do. It would require some x number of dollars, 200M, 1B, somewhere around there. A good opportunity to develop private orbital flight was missed when Beale Co went out of business here in Texas. Sorry, but Beal's designs were for cargo, not people. His design could have helped speed things up, but his rockets were not for putting people in space. A former banker I could be wrong, but I think he still is a banker. tried to develop a low-cost booster rocket to compete in the sat launch market. He figured he could sell his boosters for $200M, make a good profit, and beat Boeing and others in price. I seem to recall he was also trying to develop his own engines, which I think was a mistake as the Russians have a comparative advantage in this area. No they don't. Beal was using Hydrogen Peroxide for an oxidizer, the Russians do not have a large peroxide engine available. The booster designs at Beale featured wound carbon construction, not unlike a large cardboard shipping tube. I think that his company could have succeeded with 1) a high demand for satellite launches and 2) more capital. The weak market for sat launches is not Beale Co's fault. Then there was the unspoken factor of being the new guy, and since the Pentagon and NASA are used to dealing with the major industrial companies, Beale would have had a hard time getting a foot in the door. The amount of capital that Mr. Beale put in to the company was significant, probably $200 million. Some how you forgot the SLI program, with this Beal found himself competing directly against the government of the USA itself. He could see this was unwinnable. The government had declared SLI would meet thier future needs and that they would not need to buy other matching flights. Earl Colby Pottinger -- I make public email sent to me!
